*THIS IS AN UNTESTED THEORY BUILD THAT IS BEING TWEAKED*
The reason for the Lightning back bar is so that the tank can create off balance so that the group can utilize Stuhn's; the back bar can be changed to an ice staff depending on ZERG leader's wishes or tank preference. If you take the lightning staff off I would suggest not running the wall and running "Expunge and Modify" to help with Resources this can also be swapped for "Proxy Det." Last thing is you can run the Mage Mundus if you wish for Mag recovery, but I would just run 3 Tri-recover glyphs on jewelry (or straight mag glyphs) with a mix of Healthy, and infused maybe even Harmony, with Tri-stat on bigs ( Chest, legs and Helm) impen the rest Health glyphs ( Gloves, boots, waist, and shoulder) in Divines or trait of your Comfort . For gear sets this is up to you, but in theory "Durok's Bane" and " Frozen Watcher" presents good debuffs as well as some passive damage with the caps to Resistances the tank should be alright. for helm we are going with a HEAVY Thurvokun head, medium shoulders for undaunted passives, but if you like you can run both in Heavy or any combination .
